Abstract: The invention relates to a device for stripping impurities from belt bands in conveying systems in the area of a drive and/or deflection cylinder of the belt band. The inventive device comprises a system support which is fastened to a belt band-supporting frame and on which at least one stripping element is arranged. Said stripping element is provided with a stripping lamella that is mounted on a lamella support and leans in a stripping manner against the belt band in the stripping position. The stripping element is also provided with a lower rotating joint which is connected to the lamella support and has a horizontal rotating shaft, the term horizontal and similar in principle referring to the operational position of the stripping element, and a spring device that acts upon the lamella support in order to press the stripping lamella against the belt band.  Said lower rotating joint and spring device are configured and disposed such that the lamella support is pivoted in a spring-loaded manner about the horizontal rotating shaft in the stripping position of the stripping lamella while slightly swiveling away and swiveling back into the operating position on the belt band when obstacles which permanently stick to the belt band hit the stripping lamella. In order to be able to use the inventive stripping device at least as a preliminary stripper showing a regular stripping performance in the cylinder area of the belt band while obtaining extended operating times even at high belt speeds which are associated with correspondingly large quantities of material, the stripping lamella is pivotally mounted on the lamella support by means of an upper rotating joint having a horizontal rotating shaft and is maintained in a spring-biased position by means of an upper spring device, the spring effect of which is in the opposite direction relative to the lower rotating joint and the spring device thereof.

Abstract: Ignition systems of the kind used to ignite a difficult-to-ignite fuel oil by using energy stored in a capacitor at a breakdown for creating an ignition arc at the electrodes of a resistive arc probe, having a semiconductor resistive film across spark electrodes of the resistive arc probe, designed to preclude interference of contaminants with conduction of an ignition arc across an established current path between the electrodes of the resistive arc probe. An air gap and a resistive arc probe are connected in series. A first high voltage power supply develops a first direct current voltage across a capacitor, which is supplied as a voltage across the air gap and the resistive arc probe. A second high voltage power supply supplies a second pulsed voltage across the air gap and the resistive arc probe, wherein the second pulsed voltage is substantially higher than the first direct current voltage, aid the second pulsed voltage jumps the gap of the air gap and thus initiates and ignition arc.

Abstract: A search system generates an index for databases by generatively sampling the databases and uses that index to identify and formulate queries for searching the databases. The generated index is referred to as a domain-attribute index and contains a domain-level index and site-level indexes. A site-level index for a database maps site attributes to distinct attribute values within the database. The domain-level index for a domain maps attribute values to database and site attribute pairs that contain those attribute values. To generate a site-level index for a database within a certain domain, the search system starts out with an initial set of the sample data for that domain. The search system generates sampling queries based on the sample data and submits the sampling queries to a database. The search system updates the site-level index based on the sampling results and uses the results to generate more sampling queries.

Granted: 2009-11-24
Abstract: The aim of the invention is to improve an existing mixing device in such a manner that for a predetermined reactor length retention time is increased and the material which is to be processed is transported at essentially the same speed irrespective of the radial distance thereof from the rotational axis. As a result, at least one row of blades is arranged on each shaft and each row of blades comprises at least two individual blades and the blades are fixed to the shaft at an incidence angle a in relation to the longitudinal axis of the shaft. The blades are curved in themselves such that the blades form an angle of incidence a on the fixing point of the shaft and an angle of incidence .szlig. on the outer diameter D<SB>A</SB>. By virtue of the fact that a row of individual blades is used instead of a continuous screw, efficient mixing of charging material and coke can be achieved, the angle of incidence is reduced from the inside to the outside and the axial speed of the particles which are to be mixed is evened out on the total cross-section of the reactor, thereby enabling a stop-type flow to be obtained.
